The National Institute of Information and Communication Technology of Japan, Nagoya Institute of Technology, and Japan Aerospace Exploration Agency have achieved the so-called "world's first successful demonstration of next-generation error correction codes, reducing the impact of atmospheric turbulence on ground to satellite laser communication".Atmospheric turbulence in ground-to-satellite laser...
The laser driven particle accelerator on silicon chips was created by two independent research groups. With further improvements, this dielectric laser accelerator can be used in medicine and industry, and even in high-energy particle physics experiments.Accelerating electrons to high energy is usually accomplished over long distances in large and expensive facilities. For example, the electron ac...
Recently, the reporter learned from Changguang Satellite Technology Co., Ltd. (hereinafter referred to as "Changguang Satellite") that the company used a self-developed vehicle mounted laser communication ground station to conduct satellite ground laser high-speed image transmission experiments with the onboard laser communication terminal of the "Jilin No.1" constellation MF02A04 satellite and ac...
The pump source, gain material, and resonant cavity are the three elements that make up a laser. Due to the selective effect of the resonant cavity on the lasing frequency, multi longitudinal mode operation is one of the characteristics of fiber lasers based on traditional resonant cavity structures, manifested as periodic beat peaks in the radio frequency (RF) spectrum and periodic fluctuations i...
Recently, Jenoptik, a German company, released its preliminary performance for 2024, delivering a record high in both revenue and profit, but also revealing hidden concerns amidst industry cyclical fluctuations. Against the backdrop of weak demand in the semiconductor equipment market and increasing global economic uncertainty, this company with laser and optical technology as its core is attempti...
